Definitions

  • the invention relates to an arrangement for direct shedding on air-jet weaving machines with a plurality of parallel packages as a yarn supply.
  • the present invention has for its object to develop an air jet loom of the type mentioned that the processing of a multi-fold yarn is simplified.
  • the invention is characterized in that the production of the plied yarn is carried out directly on the air jet loom.
  • a number of yarns and / or threads are drawn off from a yarn supply and fed to a single weft store.
  • twine Both a yarn (a single-thread, textile structure consisting of staple fibers or filaments) or a twine can be taken from the yarn supply, the term twine being understood to mean the twists formed by twisting (twisting) simple yarns.
  • a thread guide with integrated monitors is advantageously provided, this thread guide preferably being connected between the package or the thread supply and the weft thread store.
  • the weft thread store is a known element and essentially consists of a right-angled thread guide element which winds the thread coming in on the input side onto a fixed drum store. On the output side, the drum store opens into a mouth at which the weft insertion elements of the air-jet weaving machine directly attach.
  • This weft store has the task of providing a precisely measured thread length of the air jet loom.
  • This drawn off at the exit of the weft store yarn is then fed to the weft insertion organs of the air jet loom, such as. B. the main nozzle.
  • the weft store therefore takes over separately at its entrance supplied yarns and twists simply in parallel form, ie these yarns and twists are brought into parallel form in the weft store, so that the multiply folded yarn is present at the exit of the weft store without twisting.
  • the arrangement according to the invention is multiplied, not only a weft store but also a plurality of weft stores and each weft store now being supplied with a number of yarns or twists via a corresponding number of cross-wound bobbins or yarn stores.
  • the thread guide with the integrated break monitor is arranged between the package or the yarn supply and the weft store, because only in this way could a weft break of an individual yarn or thread be determined.
  • 1 is an air-jet weaving machine
  • 2 is a weft store
  • 3 is the one at the exit of the weft store the weft store produced multiple fold yarn with 4 the single yarn or thread, which is drawn off separately from the package or yarn supply 6 and with 5 the thread guide with integrated break monitor, it being important that each single thread or thread 4 has a thread guide is assigned with an integrated guard.
  • the air jet weaving machine is immediately put out of operation via the signal lines 7 shown.
  • the figure does not show in more detail that an arrangement for measuring the length of the multiple-fold yarn is assigned to the weft store 2, so that a specific length is always entered into the air-jet weaving machine via this arrangement.
  • the essential advantage is achieved that a shed device upstream of the air jet loom and working separately from the air jet loom is avoided, i. H. it saves a considerable amount of apparatus, essential sources of error are avoided and the arrangement is now simplified considerably according to the invention, because the arrangement for direct shedding means that the breakage monitors are arranged directly between the packages or the thread supply and the weft store, so that the thread is always checked for completeness becomes.
  • Another advantage of this invention is that a multi-fold yarn is produced at the output of the specialist machine, which due to its volume is wound on a large-volume spool on which only a very short length of yarn can be wound, because this is a multi-fold Yarn deals.
  • bobbins are simply used here on which yarn or twine is wound, and therefore much greater lengths can be wound on such individual bobbins, so that the process of tying yarn is greatly reduced.
